ALEXANDER CAMPBELL, OF OHARLESTOWN, MASSAOHUSETTS Letters Patent N 99,530, dated February 8, 1870.

IMPROVEMENT IN PUNC'I'U'RING AND TUBULAR STOPPERS FOR SEALED CANS.

The Schedule referredto in these Letters Patent and making part of the same To all persons to whom these presents may come:

Be it known that I, ALEXANDER CAMPBELL, of Gharlestown, of the county of Middlesex, and State of Massachusetts, have made a new and useful invention for Scaling and Discharging Oans or Vessels for hold Figure 3 is a side view of the stopper, the cduct, and

Figure 4 being a bottom view of the same.

The cap, as represented at A, in the drawings, has a 'form analogous to that of a hat, it being usually made of metal, such as tinned iron, for instance.

' It is a hollow cylinder, (0, closed at one end, I), open at the other, and there provided with a-flange or ri1n,c.

\Vheu used, it is to be insertedin the head of acan, and is to be confined therein by solder applied to the can-head and the outer edge of the flange, the whole being so to hermetically seal the can, which, previous to the application of the scaling-cap, may be supposed to have been either Wholly or partially filled with kerosene-oil or other liquid.

In connection with the cap, a stopper or cook, B, is to be used, it being provided with an educt or tube, 0,

going through it, and arranged and fixed to it in manner as represented in the drawings, such tube being open at each end, except in being at its lower extremity provided with a perlorator or cutter, D, which is extended diametrically across the tube, and is to be securely fastened to it, the whole hcing substantially as represented in the drawings.

The stopper is designed to hold the cduction-tubc Within the cap, and is to tit closely into such cap. The purpose of tho pert'orator or cutter l) is to enable a person, while inserting the stopper within the cap, to puncture its bottom, and form ahole therein, directly underneath the lower cud of thc-eductiomtube, the same being in order that by inclining the can, its liquid contents may be discharged through the eduotion-tube.

The cap also admits of a common solid stopper or cork being used in it, in place of the discharging-stopper, whenever such may be desirable.

1 claim-- 1. The discharging-stoppcr, as composed of the cork B, the cduction-tube U, and the pcrtorator or cutter 1), arranged or applied together as explained, and for use with the cap, substantially as described.

2. The cap A, as set forth, in its combination with the discharging-stopper, as described, and for use in 'a can'as specified.

ALEXANDER CAMPBELL.
